CHEMICAL-ENGINE.

SPECIFICATION forming part of Letters Patent No. 61 1,030, datedSeptember 20, 1898.

Application filed July 30, 1 897.

To all whom it may concern:

Be it known that I, THOMAS DOWN, manufacturer, of the cityof Toronto, inthe county of York and Province of Ontario, Canada, have inventedcertain new and useful Improvements in Chemical-Engines, of which thefollowing is'a specification.

The object of my invention is to devise a simple, light, andeasily-operated chemicalengine; and it consists, essentially, in theimproved construction of the cylinder, in which the acid-bottle is maderotatable instead of the cylinder for the purpose of mingling the acidand the alkaline solution, and in such details of construction as arehereinafter more specifically described and then definitely claimed.

Figure 1 is asectional side elevation of my improved engine. Fig. 2 isan enlarged'section of the acid-bottle end of the cylinder. Fig. 3 is asectional elevation of the acid-bottle and cage at right angles to Fig.2. Fig. 4 is an end elevation showing the bearing-plate on the end ofthe cylinder. Fig. 5 is a sectional plan view of the central band of theacid-bottle cage. Fig. 6 is a sectional plan view of the under side ofthe upper ring of the acid-bottle cage.

In the drawings like letters of reference indicate corresponding partsin the different figures.

A is the frame of the engine, of suitable construction, to whichfrarnethe pillow-stays B, carrying the cylinder or cylinders, areconnected. The step Ois also suitably supported on the frame of themachine.

' D is a cylinder, of which two are preferably used, though only one isseen in the drawings.

E is the hose-reel, supported on the top of the engine and provided inthe usual manner with a hollow trunnion F, connected by the pipe G withthe cylinder, which pipe is preferably provided with a three-way cock Hwhen two cylinders are used.

On reference to Figs. 1, 2, and 4 the method of supporting the cylinderwill be readily understood. A bearing-plate I is suitably secured toeach end of the cylinder. Each bearin g-plate has a downwardly-dependingflange Serial No. 646,542. (No model.)

0. extended out therefrom to fit over the pillow-stay B, to which it issecurely bolted. At the acid-bottle end of the cylinder thebearing-plate has a sleeve 19 extending through it to receive the end ofthe shaft J, a suitable stuffing-box 0 being screwed on the outer end ofthe sleeve to form a water and air tight joint between the two.Connected to the end of the shaft J is ahandle K, preferably made of thehollow form shown in Fig. 2.

V L is an extension of the handle, pivoted at d to the part K.

M is a fiat spring adapted to bear against the fiat side of theextension L near its pivot, so as to tend to retain it in the positionindicated and yet permit the extension to be drawn out at right angleswhen it is desired to revolve the shaft J.

N is a small latch centrally pivoted at the upper end of the handle K.The outer end of this latch is pivotally connected with the extension Lbelow its pivot by means of the pitman 0. Thus the drawing down of theextension L will depress the inner end of the latch N. This end normallyfits between the lugs 6, formed on the bearing-plate I. (See Figs. 2 and4E.)

The shaft J is supported within the cylin der on the bearings P and hasarms Q depending therefrom, to the ends of which a chain It is attached,which normally lies upon the bottom of the cylinder. The jarring of thischain while the engine is in motion tends to stir up the soda in thesolution. When the shaft J is rotated, the soda is still further stirredup, so as to make it combine freely with the acid poured into it. Belowthe plug S theshaft is divided to form two half-rings f and g, the twoparts being bolted or riveted together at h. A series of upright barsiare cast with each half-ring and two half-rings j and k are casttherewith and suitably riveted or bolted together, the whole of theparts just described forming a cage T, within which the acid-bottle Umay be supported. The acidbottle is loosely surrounded by a skeletonjacket V, formed of the bottom plate Z, the central band 111., and theflanged upper band n, connected together by two or more rods 0.

and the engine is then ready for use.

As the flange of the band 72 extends over the shoulder of the bottle,the latter is securely held within its jacket.

1) is a cap or plug suitably fitted to the neck of the bottle.

A is a bail suitably pivoted on two opposite rods 0 and so shaped andproportioned as to fit closely upon the top of the cap 1), and thusretain it in position. A projection q is formed on this band, which isadapted to come into contact with one of the projections 0' upon theplug S when the acid-bottle is tipped, as hereinafter described.

8 and t are lugs formed upon the bands at and n, which are shaped to fitthe recesses lb and 1), formed in the rings of the cage T. The recesses11 are formed with a shoulder, as shown, to prevent the lugs 15 passingthrough them, thus affording a support for the jacket of the bottle,which is slipped into position, as shown in Fig.

w are spring-catches connected, respectively, to the half-rings f and gand adapted to engage with the flanged band 02- of the jacket v, thussecurely retaining the bottle in position in the cage. The operation ofthe engineis substantially as follows: The extension L of the handle Kis turned outwardly and the latch N thus released. The handle is thenturned till the position of the aoidbottle is reversed. As theacid-bottle swings the bail A comes in contact with one of theprojections r, and the cap 19 is thus released, permitting the acid toflow freely into the contents of the cylinder, generatin g a largequantity of carbonic-acid gas, In case of there being any liability ofthe cap 1) sticking I form projections 00 thereon, against which thebail A will strike, giving the cap a sufficient jar to loosen it. Afterthe acidbottle has been emptied it may be removed through the plug S anda new one inserted in the cage T, a fresh charge of water and alkalibeing placed in the cylinder at the same time.
